Question

我想在提交时提交所有行。目前只提交一行。这是我发布到数据库的方式：

<?php
$editFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
  $editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
}
if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "pro_forms_in_form")) {
  $insertSQL = sprintf("INSERT INTO ho_add_stock_proforma (supplier, inv_no, `day`, `month`, `year`, product_name, descrpt, qty, cost, hawker, wholesale, retail, total) VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s)",
  GetSQLValueString($_POST['supplier'], "text"),
  GetSQLValueString($_POST['inv_no'], "int"),
  GetSQLValueString($_POST['day'], "int"),
  GetSQLValueString($_POST['month'], "int"),
  GetSQLValueString($_POST['year'], "int"),
  GetSQLValueString($_POST['product_name'], "text"),
  GetSQLValueString($_POST['descrpt'], "text"),
  GetSQLValueString($_POST['qty'], "text"),
  GetSQLValueString($_POST['cost'], "text"),
  GetSQLValueString($_POST['hawker'], "text"),
  GetSQLValueString($_POST['wholesale'], "text"),
  GetSQLValueString($_POST['retail'], "text"),
  GetSQLValueString($_POST['total'], "text"));
  mysql_select_db($database_universal, $universal);
  $Result1 = mysql_query($insertSQL, $universal) or die(mysql_error());
}

mysql_select_db($database_universal, $universal);
$query_Creditors = "SELECT company_name FROM ho_add_creditors";
$Creditors = mysql_query($query_Creditors, $universal) or die(mysql_error());
$row_Creditors = mysql_fetch_assoc($Creditors);
$totalRows_Creditors = mysql_num_rows($Creditors);

?>

您是通过Javascript向HTML表添加行，然后使用PHP添加/更新数据库中的行，是否正确？

新的HTML表行仅存在于浏览器中（您通过Javascript在客户端创建它们）：服务器上运行的PHP不知道它们是否存在，因此无法在数据库中插入/更新它们。

您需要生成HTML表格服务器端的新行并重新加载浏览器页面，否则如果您在客户端生成它们，则需要在每个POST中手动包含新行。

我需要所有的html表行提交到数据库
